Thank you for the suggestion, sirmaru. For me, when I have the light up high, it becomes more noticeable, although it's mainly only when I turn a page that I see it or if there's a black cover on my home page. I do also keep page refresh on all the time, but because I know where it is it becomes more noticeable to me now.
I noticed it because a few others mentioned having them so I scanned my screen thoroughly to check mine and I caught it. It's pretty minor, not as big as the speck another user on here posted, but I may ask for an exchange anyway as it really shouldn't be there.
